I shot IPSC with my XD45 Tactical yesterday and used the XDGear holster that comes with the gun (slides on the belt, open loop style). While it didn't give me an advantage, it worked fine. Kind of a pain to reholster but drew fine. I'm not so worried about my time, so I didn't care. In the future I'd like to get something a little better for carry, like a Serpa or something.
